Capacitor-Discharge Topology

A PEMF driver design where a capacitor is charged to a high voltage and then rapidly discharged through the coil to produce a pulse. Rise time is governed by the discharge rate (V/L), so a larger capacitor at higher voltage produces a faster, higher-amplitude pulse. The capacitor recharges between pulses, limiting maximum repetition rate. This topology is well suited to producing very high slew rate pulses at low-to-moderate frequencies.
